Mainland southeast Asia, also known as the Indochinese Peninsula, refers to the continental portion of Southeast Asia[1] lying roughly south or southwest of China, and east of India. The historical name "Indochina" has its origins in the French Indochine, a combination of the names of "India" and "China", referring to the location of the territory between those two countries.

The countries of mainland Southeast Asia however received cultural influence from both India and China to varying degrees.[1] Some cultures, such as those of Cambodia, Laos, and Thailand are influenced mainly by India with a smaller influence from China. Others, such as Vietnam, are more heavily influenced by Chinese culture with only minor cultural influences from India, largely via the Champa civilization that Vietnam conquered during its southward expansion.
